Lost earring. Greystones, Co. Wicklow

I lost an earring in Greystones rugby club yesterday evening, Wednesday 13th September. I have a very good idea where I lost it so the search area shouldn't be too large. I tried using a "builders" detector but I don't think it was sensitive enough.
My email is galway_grey@yahoo.ie if anyone local would be willing to have a look for it. Getting permission from the club shouldn't be an issue.
